Reason: This AD was prompted by a report of rudder control pushrod failure during a production ground run caused by sheared rivets off of a rudder control pushrod. The FAA is issuing this AD to detect and address incorrect rivets. The unsafe condition, if not addressed, could result in rudder jam or loss of rudder control, which could lead to loss of control of the airplane during flight or ground operations.
Required actions:
(1) Within 20 hours time-in-service or 30 days, whichever occurs first after the effective date of this AD, do a visual inspection of the attaching rivets of the pilot and copilot rudder control pushrods for incorrect rivets in accordance with the Accomplishment Instructions, paragraphs 4 and 5, of Beechcraft Mandatory Service Letter MTL-27-07, dated July 25, 2025.
(2) Depending on the results of the visual inspection required by this AD, do the following, as applicable:
(i) If two soft rivets are found adjacent to each other on the same rod end for one rudder control pushrod, before further flight, replace with rivet part number MS20470AD4-12 in accordance with the Accomplishment Instructions, paragraph 7, of Beechcraft Mandatory SL MTL-27-07.
(ii) If one soft rivet and one hard rivet are installed on any of the four rod ends, within 200 flight hours or 12 months of the visual inspection required by this AD, whichever occurs first after the effective date of this AD, replace the soft rivet with rivet part number MS20470AD4-12 in accordance with the Accomplishment Instructions, paragraph 7, of Beechcraft Mandatory SL MTL-27-07.
